CUSHION-COVER FOR THE SEATS AND BACKS CHAIRS.

Application filed March 8, 1917. Serial No.

To all whom it may concern:

Be it known that I, ROBERT SrrnINMnTz, a citizen of the United States, and resident of Rochester, in the county of Monroe, in the State of New York, have invented new and useful Improvements in Cushion-Covers for the Seats and Backs'of Chairs, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvefor the seats and backs of chairs, the type commonly used in barber shops, dental parlors and other places which are patronized by the general public.

It is well known that when an upholstered chair of this type has been occupied by a patron for a relatively short time, the bodily heat of such patron is transmitted to and retained for a greater or less period of time by the seat and back so, that, if no provision is made for cooling those parts, the succeeding occupantis forced to undergo the discomfort from the excessive heat radiated by such parts in addition to a feeling of insecurity from a sanitary point of view.

he main object of my invention is to overcome these objectionable features in as simple and without materially altering the standard types of chairs to which my invention may be applied. In other words, I have to avoid the objectionable heat by providing the seat and back of the chair with movable covers and the covers may have become heated by one occupant, may be shifted to an exposed position for ventilation and cooling while another cooler and ventilated portion may succeeding Other objects and uses relating to the covers and their operating means will be brought out in the following description.

In the drawings- Figure 1 is a perspective view of a chair equipped with my invention.

means for transmitting motion from the crank shaft to the cover-feeding rollers, showing also the adjacent portions of the seat and back and side arm.

Fig. 4 is a detail sectional view through a portion of the lower edge of the back showing the adjacent portions of the back cover and feeding means therefor.

As illustrated, the chair comprises an upholstered seat -A- and back -B-, both mounted upon a supporting frame -C* so that the rear edge of the seat and lower edge of the back will be in spaced relation to allow free movement of the covers, presently described, therethrough, and also to allow the back to be tilted to different angles in the usual manner not necessary to herein illustrate or describe.

fabric of low heat conductivity of approximately the width of the parts to which they are applied, the cover -lbeing extended forwardly and rearwardly around the front and rear edges of and under the seat A- while the cover -2 is extended around the Uooer feeding means.

The means for feeding the covers across the faces of their respective parts -A and B- preferably comprises separate rollers -3- and which are journaled at their ends in opposite sides of the frame -C- just below the rear edge of the seat and just at the rear of the lower edge of the respectively.

These feed rollers are provided at one and the same end with gears 5- which mesh with an intermediate driving gear 6, the latter being secured to a crank shaft -7- on the adjacent side of the frame C and provided with a hand crank -8- for turning the same and thereby rotating the feeding rollers for shifting both cover-belts 1- and -2 simultaneously.

-3- and. -4- extend transversely of and between the sides of the frame in parallelism with their outer faces, substantially coincident with the adjacent edges of their respective parts -A and Similar rollers or idlers -9- are journaled at their ends in the sides of the frame -C- near the lower front edge of the seat --A- and near the upper rear edge of the back -B- respectively and cooperate with their respective feed rollers -3 and --4: to hold the lower side of the cover --1-- and rear side of the cover -2- clear from the corresponding sides of the seat and back so as to expose these portions of the covers for cooling and ventilation while the opposite sides are in use.

In order to prevent slipping of the feed rollers 3- and lrelatively to their respective covers -1 and -2- l have provided additional pressure rollers -10- ant -l'ls which are journaled at both ends in movable bearings -l2- parallel with and adjacent to their companion feed rollers 3- and -4-, said bearings being springpressed toward their corresponding feed rollers by springs 13 to firmly impinge the interposed portions of the covers against said feed rollers so that when the feed rollers are actuated by the turning of the hand crank -8 in either direction, both covers will be positively and simultaneously shifted longitudinally across the faces of their respective parts and The backs -B- of chairs of this type are usually tiltable and under these COIL ClI- tions the crank shat -4 is coaxial with the axis of movement of the back so as to keep the gears --5- in mesh with the driving gear -6 and the shaft 7 may therefore constitute the turning connection between the back-supporting section and ina-in body of the frame What I claim 1s:-

In combination with the'main frame of a chair having a seat and a back hinged to the frame near its lower edge to swing forwardly and rearwardly, rollers supporte wholly below the bottom of the seat near the front and rear edges thereof, an endless belt covering extending across the top and front and rear edges of the seat and around the underside of the rollers, a pressure roller springpressed' against theunderside of the belt covering directly under the rear roller, additional rollers wholly at the rear side 0 the back near the lower and upper e thereof, a separate endless belt covering extending across the front and lower and upper edges of the back and around the rear sides of said additional rollers, and an additional presser roller spring pressed against the back covering at the rear of its lowermost roller, gears secured to one end of the rear roller of the seat covering and lower roller of the back covering, respectively, an intermediate gear meshing with said gears and substantially coaxial with the axis of movement of the back of the chair, and means for rotating said intermediate gear for effecting the simultaneous operation 0 both endless belt coverings for the seat and back.

In witness whereof I have hereunto set my hand this 24th day of February, 1917,
